70 | Katie Mack on How the Universe Will End

Cosmologists are always talking excitedly about the Big Bang and all the cool stuff that happened in the 14 billion years between then and now. But what about the future? We don't know for sure, but we know enough about the laws of physics to sketch out several plausible scenarios for what the future of our universe will hold. Katie Mack is a cosmologist who is writing a book about the end of the universe. We talk about the possibilities of a Big Crunch (and potential Big Bounce), a gentle cooling off where the universe gradually grows silent, and of course the prospect of a dramatic phase transition, otherwise known as the "bubble of quantum death." Which would make a great name for a band, I think we can all agree.
